I am having classloading issues when I include hibernate JARs in my war. jars have to be included in the war because the application needs to be able to select hibernate version freely.

My application uses hibernate to implement JPA.

I have tried to override universal classloader with jboss-web.xml:

<jboss-web>
<context-root>/</context-root>

<class-loading java2ClassLoadingCompliance="false">
<loader-repository>
org.myapp:loader=hibernatetestclassloader
<loader-repository-config>java2ParentDelegation=false</loader-repository-config>
</loader-repository>
</class-loading>

</jboss-web>

But no success. the error I am experiencing is

java.lang.ClassCastException: org.hibernate.search.event.FullTextIndexEventListener

I have created a simple test application to recreate the problem.

Once you have deployed the war, you should be able to go to

http://localhost:8080/myproject-1.0-SNAPSHOT/mainMenu.html or
http://localhost:8080/mainMenu.html

(depending on whether you are using tomcat or jboss)

and see a list of users from app_user database table. app_user should have two fields, "id" and "username". This war assumes you have MySQL running on localhost, and have user "root" with password "erofog". Or you may change the username and password in jdbc.properties in WEB-INF/classes/

You should be able to see whether you get deploy-time classloading errors or not, even if you don't have a MySQL server at all. So mysql is not really necessary. If you don't have mysql you will still get some deployment time errors, but deployment should be successfull and you can access the page and get something like:

javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: Cannot open connection

I have tested on

1. tomcat 6.0.14 - works fine
2. JBoss 4.0.3SP1 - works fine
3. JBoss 4.2.1.GA - I get:
